“…This research will focus exemplarily on the task of planning the location of cranes on construction sites [7]. Cranes often constitute a bottleneck resource that leads to delays as crews wait for material or components to be lifted.…”

-A temporal-spatial scheduling model is used to consider the location and movement of equipment, material and temporary structures on a construction site over time, ensuring efficient yet safe processes. The model ties together activity scheduling and dynamic site layout planning, fully integrating two domains that have so far been treated separately. Their integration is facilitated by modeling temporary site objects like cranes as singularity functions. These objects are explicitly linked in the model with work spaces through Boolean operators.

“…As a vital productive resource on site, arguably the most important one [7] due to supplying many trades with materials and assemblies, cranes -here specifically tower cranes -have a dominant role. The operating area of such crane is cylindrical, where the mast is located at {x1C, x2C}.…”

This paper builds on previous research by the authors which determined the global state-of-the-art of constructing tall buildings by surveying the most active specialist tall building professionals around the globe. That research identified the effect of wind on tower cranes as a highly ranked, common critical issue in tall building construction. The research reported here presents a design for a "Lifting Wing," a uniquely designed shroud which potentially allows the lifting of building materials by a tower crane in higher and more unstable wind conditions, thereby reducing delay on the programmed critical path of a tall building. Wind tunnel tests were undertaken to compare the aerodynamic performance of a scale model of a typical "brick-shaped" construction load (replicating a load profile most commonly lifted via a tower crane) against the aerodynamic performance of the scale model of the Lifting Wing in a range of wind conditions. The data indicate that the Lifting Wing improves the aerodynamic performance by a factor of up to 50%.

“…Therefore, onsite production process is being replaced mainly by installation of the elements and material which is transported to the site. Consequently, material handling devices are becoming more and more dominant in building construction sites (Shapira et al, 2007). Among all material handling devices, cranes, including tower and mobile, are the most popular ones.…”

Today, with the necessity of timely, on-budget and high quality completion of projects, proper use of construction equipment is essential to ensure project success. Construction equipment places a large monetary burden on the project and if not utilized efficiently, it can result in economic losses. Cranes are one of the most important and expensive operational devices on construction sites. They play a central role, and often activities that rely on crane services fall on the project's critical path. Currently, material-handling scheduling is done by the crane operator or by an on-duty superintendent using his/hers personal judgment, making the process manual and timeconsuming. Thus, developing an optimal schedule, which considers different dynamic constraints in construction job site, may not be possible based on the current practice. This leads to longer operation times and a negative impact on project cost. This paper presents the latest results of an ongoing study, which aims to design and implement a nearreal time crane operation decision support system to be utilized directly by the crane operator or as an aid for the superintendent in scheduling optimal operation services. This system has several advantages such as maximizing the efficiency of crane operations, guaranteeing the best operation possible to reduce the crane's travel time, reducing crews and equipment idle time, and minimizing the dependence on subjective human judgments.
